دراسة تحليلية طيفية لتحسين شروط تحديد عنصر الزنك باستخدام الكاشفBPT وتطبيقها على بعض الصخور السورية
Abstract
تم في هذا البحث تحسين شروط تحديد الزنك الثنائي في الصخور السورية الساحلية في منطقة الباير والبسيط شمال اللاذقية باستخدام طريقة التحليل الطيفي الضوئي بالاعتماد على تشكيل معقد مع BPTعند الطول الموجي (430nm) من خلال دراسة تأثير درجاتpH الوسط, وتأثير التداخل الناتج عن وجود بعض الأيونات:النيكل, والحديد الثنائي, والكالسيوم، والنحاس، والكروم, والمنغنيز التي تعيق عملية تحديد الزنك بوساطة الكاشف BPT والتي اختلفت نسب إعاقتها وفق التسلسل الآتي: Mn2+>Cr3+Downloads
